The solution allows encapsulating the generated packet data within GTP headers and transmitting through the gateway points such as SGSN & GGSN, or SGW & PGW.
GGSN: GGSN is the key equipment of GPRS network connecting other networks.
Core network connectivity emulates the SGSN operations to communicate with the UMTS GGSN.
If HA is deployed at gateway GPRS support node (GGSN), all incoming packets from the Internet to an MT are routed via GGSN and average packet-delay increases when the MT is in loosely-coupled WLAN.
It enabled us reducing CAPEX and OPEX by combining both GGSN and charging session control all in one box" said Jalel Kamoun, VAS and Prepaid director at Tunisiana.
El GGSN 'G' desempaqueta el GTP, retira el pedido original del movil y lo encamina hacia el firewall 'F' de salida hacia Internet.
CGE is targeted for edge and core telecommunications including applications for the converging IP and voice networks such as softswitches, SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node), RNC (Radio Network Controller), voice over IP (VoIP) gateways, and many other applications.
On the other hand QoS concept and architecture for UMTS network as specified in 3GPP  focuses on QoS signaling from user equipment to GGSN only and it does not support the QoS mechanisms for data transport.
MobileNext Broadband Gateway: Providing GGSN and PDN/Serving Gateway functions in one platform, the MobileNext Broadband Gateway delivers scale and performance with uncompromised in-line IP services while enabling service creation with the Junos SDK for operators to innovate profitable data services.

3), la calidad de servicio requerida, la direccion IP del SGSN y GGSN que soportan la sesion, etc.
Aditya Kaul, practice director of mobile networks says, "Mobile packet core spend has always been dominated by 3G WCDMA packet core elements like GGSN and SGSN, but that seems to have peaked recently.
